Tube Facing & Squaring Machines

Orbitalum RPG 4.5 Tube Squaring Machine


In orbital fusion welding, it's imperative that the tube ends are perfectly square, clean and burr free so the resulting weld is defect free. While our GF series of stainless steel tube saws cut precisely, for best results tube ends require machining prior to orbital welding. Machining the open end of the pipe or tube is a process called squaring, or facing. Orbitalum’s RPG series of tube facing machine tools are the high purity industry standard, delivering precise and repeatable results. They're used by process piping and high purity installation professionals in Aerospace, Pharmaceuticals, Food & Beverage, Semicon and other industries.

The RPG series provides ease of use with quick clamping, with long lasting precision clamping shells. The capabilities of our RPG range include facing (or squaring) I-seam thin-walled stainless steel tubes and fittings, as well as unalloyed and low-alloyed steels and titanium. The RPG facers can be bench mounted or portable, with many available in a choice of corded or cordless. Users can select the appropriate clamping shells from the range of accessories for each diameter.

The quick tool change system allows clamping shells and workpieces to be easily changed without additional equipment. All multi-functional tools (MFW) cutting tool bits are two-sided, with protective coating against premature tooling wear. This enables the preparation of tubes made of high-alloy, unalloyed and low-alloy steels with high precision, quickly and efficiently.

Cordless versions of the RPG machines are ideal in situations where access to power service is limited, or where portability is a prime consideration. The machines and accessories are supplied in a handy, durable storage and shipping case – the cordless versions are offered with a 120V charger for the American market or a 230V charger for the European market.
